Vitiligo: Overview Vitiligo: This skin disease often forms on both sides of the body as shown here on the knees. Vitiligo (vit-uh-lie-go) causes the skin to lose color. Patches of lighter skin appear. Some people develop a few patches. Others lose much more skin color.
Removing and inspecting spark plugs tell you a lot about how well the engine is running and what may be causing problems. All spark plugs should be removed and checked every 30,000 miles - even if your BMW is low maintenance - you're told to change spark plugs at 100,000 miles. This prevents the plugs from seizing in the block, causing expensive repairs down the road. Always note which plug came from which cylinder.
After the spark plugs have been in the engine for a while, carbon deposits form around the spark plug tube, between the spark plug and the cylinder head. The carbon causes the lower half of the spark-plug shell to stick in the head and separate from the upper shell when the spark plug is turned for removal.he towing was $110.50, the eight new spark plugs cost $104.72, and the Ford dealer charged $323.68 for broken-plug removal labor. The grand total was $538.90, a high price to pay for a spark plug change.
